Our cities are characterised by modernist town planning principles which have fragmented communities through spatial barriers such as highways, train lines and fences while current development perpetuates urban sprawl. Due to these circumstances many contemporary urban design policies promote densification strategies through transit orientated approaches. In my thesis project, I propose to redesign Salt River Train Station into a multi modal transport interchange. I argue that this multimodal interchange can have an urban developmental and regenerative effect that can address some of the challenges faced in our urban landscape. This design report will attempt to document the processes and explorative methods that I have incorporated during this design process. In section A, I will give an overview of the issues regarding transportation and land-useland-use in South Africa - and Cape Town in particular- and summarize theories that attempt to address these issues. In addition, I will also give an overview of key areas of research that were relevant and informative to the project. I will then briefly discuss theories that have guided me during the design process.process . The focus falls particularly on Heidegger and his theories of dwelling - which I believe is fundamental to the architectural project - followed by the mapping theories of James Corner as a design tool. The document will also summarize the technical studies that acted as a precedent for the making process and materiality. In section B I will focus on the exploration of design ideas. Here I will document the processes and methods that were used to design the overall project. I will attempt to show how I have used and merged the theories and information researched to manifest in the building concept. The main focus of this part of the document will be the visual and descriptive documentation of the conceptual development and exploration of the project through mapping, drawing, model building and 3D computer processes. Plans and sections will show a more detailed representation of the building design process but should not be seen as conclusive drawings. This will be included in the Appendices at the end of the document. University of Cape Town Section A The current transportation debate in South African Cities Urban sprawl has become a major spatial development characteristic of South African cities . The effects of poorly integrated transport and land use planning are highly evident in the low population densities that are common in our cities, and the long distances that people are often forced to travel as a result. This situation is socially, environmentally and economically unsustainable. The majority of the population is forced to live in segregated, isolated and hostile townships, separated from each other by freeways and buffer zones. This has created a vastly inequitable and inefficient city in which the poor are marginalized from urban opportunities (Pistorious, 2002). According to Beukes and Vanderschuren (2009), the problems are further compounded by historically poor investment in public transport infrastructure, especially in poor neighbourhoods. The net result is that it is often the poorest people in urban centres who spend the largest percentage of their disposable incomes on transport costs. How can some of these spatial issues be addressed? Laying down the principles Efforts are increasingly being made to enhance the role of transport in order to improve the social and economic conditions of South Africa. This is evident in the preparation of documents such as the Integrated Transport Plans and Spatial Development Frameworks which are intended to encourage the transformation process. Williams (2009) explains that "South Africa's changing context is driven mainly by political imperatives for transforming the built environment to improve social equity and economic inclusion, overcoming the separation of home and work with more effective transportation, reducing transport costs for users while improving financial viability of public transport servicesservices."." Williams (2009) argues that a few key responses and principles are needed to implement changes, in particular: The treatment of transport nodes, or interchange hubs and their surrounding precincts, which is critical to the success of the system as a whole. Safe, convenient access to the transport system depends on good urban design, and a more considered approach will serve multiple policy sectors, such as health, education and labour. A key challenge is defining project briefs that are broad enough to allow for effective interventions.interventions. University of Cape Town Beukes and Vanderschuren (2009) also argue that the guiding literature for transportation planning in South Africa emphasizes the importance of encouraging a multimodal transportation environment that addresses the economic inequities in our towns and cities, that protects the environment from the effects of transportation, and that stimulates the development of a healthy social realm. In addition, the inseparable relationship between transportation and land use is emphasized and planners are encouraged to view land use and transportation as being almost two sides of the same coin. Land use and transportation are therefore intrinsically linked, as changes in land use often initiate changes in trip making patterns, and vice versa.versa . Many factors contribute to economic and social progress, but multi modal mobility is especially important because the ingredients of satisfactory life, from food and health to education and employment, are generally available only if there is adequate means of moving people, goods and ideas. (Owen, 1987) Dewar and Uytenbogaardt, (1991) argue in favour of the creation of a compact, intensive and convenient city which operates as an integrated system, which works well at the level of the lowest common denominator (people on 2 foot), which makes maximum use of limited resources and which is respectful of its beautiful natural setting. Cape Town Transport system characteristics According to the Integrated Transport Plan (ITP 2006) Cape Town has a relatively extensive but poorly integrated public transport system, the backbone of which is its rail system, which is depicted in image 1. Providing transport across the greater part of the metropolitan area is the bus service operated by Golden Arrow Bus Services under contract to the Provincial Government of the Western Cape. Service frequencies are very low on many routes and night services are extremely limited. Both rail and bus services are subsidisedsubsidised.. Unsubsidised services are provided by minibus taxis, which operate over most of the metropolitan area, providing greater penetration than other modes, especially in low income, high-density residential areas. The City also has an active metered taxi component, one that has recently seen some growth in demand through the introduction of shared metered taxi services. Finally, these services are backed up by more tourist oriented bus services, such as the City Hopper, which operates on key scenic routes around the City. In support of tourist activities, additional train services are operated during holiday service that caters for registered special needs users. The Cape Town Spatial Development framework (SDF) sets out the following objectives in order to promote a more sustainable Cape Town with an effective urban form and urban and regional planning for the city: • Promote integration between areas to improve access, and increase the economic potential of marginalised areas.
